Kenworth Truck Company in Chillicothe manufactures heavy-and medium-duty trucks. Approximately 2,000 employees work at the plant, producing about 150 trucks per day. The first Kenworth truck rolled off the Chillicothe assembly line in 1974. The plant’s milestone 500,000 truck was produced in February 2016. The 420,000 sq. ft. building houses manufacturing, warehousing and administration offices. The plant operates two manufacturing shifts and one maintenance shift on a 24-hour-a-day, 5-days-a-week work schedule.

In 2017, Kenworth received recognition as an Ohio EPA Encouraging Environmental Excellence (E3) Silver Level Awardee  for the following sustainable activities.

  • Implementing energy savings programs involving compressed air, machine maintenance and optimization, air conditioning settings and installing occupancy sensors.
  • Reducing and eliminating wastewater and storm water. They now re-use storm water as a dust suppressant on the facility’s gravel roadways and parking areas.
  • Becoming a Zero Waste to Landfill facility. Materials are now being recycled or sent to a waste-to-energy facility. These include hazardous and universal wastes, plastics, metals, glass, cardboard, paper, wood, pit and sump slurry wastes and wastewater treatment plant sludges. Plastic drums from raw product are now reused. More than 16 million pounds of material were recycled in 2016.
  • Incorporating a spent solvent recovery system where solvent used to purge paint lines is reclaimed and reused. Approximately 70 percent of the spent/waste solvent stream is recovered as usable solvent.
  • Converting to returnable rack systems for internal parts, removing 1,994 tons of cardboard from the waste stream.

The E3 program provides four recognition levels: Achievement, Silver, Gold and Platinum. Any organization in Ohio may apply for membership. Applications are accepted annually and include both written and on-site evaluations. To be eligible, applicants must be in compliance with environmental laws and rules.
